Some of these are a continuation of January tasks.
Lawns will look like they need some attention. It's too early to sow new seeds so:
If the weather permits aerate the surface using a spiking machine or in smaller areas, a garden fork (we like to follow a herringbone/argyle pattern!).
Keep the surface free from leaves, twigs and other debris. This helps keep the turf dry and reduces the risk of disease.
Mowing possibly once or twice, to maintain a regular height of cut is advisable (hover mower if the soil is moist).
Fertilise the soil.
Sow sweet peas under a cloche or in the greenhouse for a cheery reminder that spring is on the way.
Firm any plants lifted by frost and begin trimming established hedges.
Evenly spread garden compost or well-rotted manure. This will keep your soil in good condition and help with its structure (especially for compacted areas).
Stock up on nematodes - a unique organic solution to control caterpillars, Codling Moth & Gooseberry Sawfly, snails, slugs, Vine weevil and many more beasties.
Check for bugs, fungus and abnormalities – we have had a very mild Autumn//winter which has not yet killed all bacteria and fungi.
If unsure you can contact the RHS for help (RHS members can send samples for assessment).
